  • Patent number: 4608735
    Abstract: A molded sliding bar buckle of the type comprising a strap retainer bar slidably mounted on an open rectangular connector frame having a grip base and a connecting bar on opposite sides of the strap retainer bar. The strap retainer bar includes a central strap engagement portion for retaining therearound one end portion of a strap and having on its back a sloped flat or substantially flat surface facing away from the grip base. The sloped surface has an upper end disposed adjacent to the connecting portion and a lower end disposed adjacent to the grip base, the upper end lying in a plane extending through a center of the thickness of the strap engagement portion. With this construction, when the strap is longitudinally tensioned with its one end portion looped around the strap engagement portion, a tensioning force is transformed substantially into a force or a vector acting in said plane in a direction to tend to move the strap retainer bar linearly toward the grip base.

  • Patent number: 4571783
    Abstract: A strap fastener or buckle for connecting ends of a strap, belt or the like is adapted to enable adjustment of the effective length of the strap. The strap fastener is formed from a plastic material into an integrally molded structure having a grip head portion at one end and a connecting portion at the opposite end, these portions being connected by a pair of side flanges. A pair of spaced parallel cross bars extend between and are connected to the side flanges. The grip head portion has a sharply cornered bottom edge which serves as a stop for the strap. The cross bar which is disposed adjacent to the grip head portion has a plurality of sharp corners defining stops for the strap, one of the corners being disposed adjacent to the grip head portion and being spaced in plan view from the bottom edges by a distance larger than the thickness of the strap. The strap fastener is thus provided with multi-point stops along the path of the strap so that the strap can be retained firmly in place under heavy tension.

  • Patent number: 4562624
    Abstract: A snap fastener for use on garment pieces comprises a male member attached by a first rivet to one of the garment pieces and a female member attached by a second rivet to the other garment piece. The male member includes a first cylindrical wall having an annular rim snapped in an annular groove defined in a second cylindrical wall of the female member. The male member and the first rivet have reinforcing ribs biting in the garment piece sandwiched therebetween, and similarly the female member and the second rivet have reinforcing ribs held in biting engagement with the garment sandwiched therebetween. The male and female members, and the first and second rivets are prevented by these reinforcing ribs from rotating with respect to the garment pieces, an advantage which manifests itself especially where the first and second rivets have directional ornamental patterns on their heads.
